Quite a few users over on Phandroid love the 4000+ mah batteries found on Amazon for $15-25 .. I see Seidio is releasing theirs soon for $70 range. All claim to keep NFC. With all that said does anyone have any experience with these items or anything related ?

I used qcell one for a week and battery life literally doubled. I used it with my gps with Max brightness from NY to VA last weekend which takes about 8 hours and my phone survived throughout the trip. But I didn't like How thick it becomes so chose to go back to regular one and use the extended one for a long trip or something.

Do you know of any cases that will fit? ie: Trident Aegis, Otterbox or the like? Really thinking of getting an extended battery, but only if the phone will fit in a case. I'm clumsy! Lol.

The third-party extended batteries make the S3 far too thick for any of the standard cases out there. The only case that I'm aware of that will fit the S3 with one of the large extended batteries is this one made by Hyperion. The description says it should work with the extended battery and cover from nearly all of the third-party battery manufacturers.

Thanks for the quick reply. While I'm not too fond of TPU caes, I may just have to bite the bullet and buy it... as I'm also not fond of horrible battery life. Haha!

This is what I got. Honestly, it fits perfectly in size, but there's a problem. Volume button and lock button parts are covered and it's kinda hard to press it. Thankfully, my mother in law, who got a pink one, cut those parts with scissors and it worked just fine for me. Hope this helps.

And here are two more extended battery TPU cases that claim to fit with pretty much all of the third-party extended batteries - Blue, White. These are made by QCell. They don't look quite as nice as the Hyperion case, but they're a little cheaper and qualify for Amazon Prime.
